Twine treating mixtures and twine treated therewith



ilnited States Patent C) TWINE TREATING MIXTURES AND TWINE TREATEDTHEREWITH Clarence Louis Ederer, Gwynedd Valley, Pa., assignor to EdererCorporation, Philadelphia, Pa., -a corporation of Pennsylvania NoDrawing. Application November 1, 1952, Serial No. 318,345

2 Claims. (Cl. 106-212) This invention relates to yarn or twine treatingmixtures and also to yarn or twine treated therewith, particularly hardtwisted or braided yarns or twines of flax, other bast fibers, cotton,synthetic fibers or the like intended for use as harness twine inJacquard mechanisms of looms employed in weaving fancy or ornamentedfabrics. In the past, such yarns or twines have been treated with astarch solution to strengthen and reinforce them and, after drying, tocoat and polish them with graphite for the purposes of lubrication andresistance to wear. This two-stage treatment was time consuming and didnot result in penetration of the twines by the graphite, with the resultthat rapid wear of the twines took place after breaking down of thecoating through abrasion with guides or metal parts of the Jacquardmechanisms.

My invention is directed toward overcoming the above drawbacks. Thisobjective is realized in practice, as hereinafter more fully disclosed,through provision of a combined impregnating and coating preparationwith which the yarn or twine can be treated in one operation tostrengthen it and at the same time render it more resistive to rapidwear.

In carrying out my invention, I prepare a new treating mixture bymechanically stirring a quantity of colloidal graphite into cold water,and by incidentally adding quantities of a suitable starch or starches,beeswax and/ or other waxes.

A mixture produced with ingredients of the following proportions hasgiven highly satisfactory results in practice.

4 lbs. of colloidal graphite dispersion in 1% gallons of water.

10 lbs. of potato starch.

10 lbs. of tapioca starch.

4 lbs. of beeswax.

2 lbs. of carnauba wax.

Suflicient water to make gallons.

To treat the yarn or twine, I soak it in the hot mixture of colloidalgraphite, starches and waxes until thoroughly saturated, and then afterdrying and setting of the treating medium, I polish the yarn or twine toprovide it with a smooth hard wear-resistant surface.

It is to be understood that I do not consider myself limited to theprecise proportions of the ingredients herein given above by way ofexample, since the proportioning can be varied depending upon theabsorptive characteristics of the material from which the yarn or twineis spun, and upon the degree of stiifness and lubrication desired in theyarns or twines.

Having thus described my invention, I claim:

1. A fluid impregnating and coating composition consisting of a mixtureof four pounds colloidal graphite, ten pounds of potato starch, tenpounds of tapioca starch, four pounds of beeswax and two pounds ofcarnauba wax and water in sufiicient quantity to render the compositionfluent.

2. As a new product of manufacture, polished twine for loom harnessesimpregnated and coated with the composition defined in claim 1.
